Another thing that I noticed is that the sorting is often not applied anymore. There I also have to uncheck and re-check any of the filters, or switch between sorting modes so that the correct sorting is applied.

Ah, well if this is not a general issue, then I'll try to disable some of my UI mods just in case they interfere with this. In any case here is one of the recent logs: game_18548967.log

I'm still having issues - it did get better (less errors just) for a day or so, but the last couple of days seem to be back to the new normal of hardly being able to launch/join much.

I see, thank you :). And I agree, it's just annoying and not critical.

If you want to do it nobody is stopping you. I just don't expect anybody to do it for you because there is no benefit of doing that aside of personal curiosity of finding out how things work.
